<P>PROBLEM TO BE SOLVED: To precisely detect timing of a changing point when a signal level is changed in an output signal output from an electronic device. <P>SOLUTION: This detector is provided with a changing point detecting part for receiving the output signal from the electronic device to detect the changing point, a signal level detecting part for detecting the signal level of the output signal before or after the changing point in the output signal, and a correction part for correcting the timing of the changing point detected by the changing point detecting part, based on the signal level of the output signal detected by the signal level detecting part. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
